Re: Survey...
I'm surprised no one has mentioned waze - it's much more focussed on the driving experience than Google Maps. The community call in of hazards ahead works well to alert you of weather, traffic and other "things to be aware of" (eg lurking boys in blue). It's prediction of trip time is usually within a few minutes, even on a journey of hundreds of km. And it will re-route you around road closures and very bad traffic conditions - saved me a few times when the M25 gets randomly shut in the wee hours with no hint of a diversion route.
